suggestion: add 25 MHz to list of time stations
Although WWV stopped officially transmitting on 25 MHz decades ago, it still transmits there unofficially. Since it's one of the few stations transmitting continuously on such a high HF frequency during this part of the sunspot cycle, I find it a useful beacon for band openings. I hear it in San Diego every time there's an E-skip opening (like right now). In fact I'm hearing WWV on all 6 frequencies, which is pretty unusual.
